Tracking user activities in your organization’s Microsoft 365 environment isn’t just about security and compliance—it’s about staying one step ahead of potential threats. As an IT administrator, staying vigilant means regularly monitoring user sign-ins. Understanding Entra ID sign-in logs is crucial; they provide detailed insights into who accesses what and when, helping you spot anomalies that could indicate suspicious activity.

Let’s dive into the methods available to access Entra ID sign-in log activity details.

How to Analyze Microsoft Entra Sign-in Logs?

The following are the available methods to check user sign-in logs in Microsoft Entra ID.

Microsoft Entra Admin Center: Sign in to the Microsoft Entra admin center and navigate to Identity –> Monitoring & Health –> Sign-in logs. Here you can find the list of sign-in events of users in your organization. However, the sign-in logs in the Entra admin center are limited to the past 30 days.

Unified Audit Logs: Navigating through the Unified Audit Log using ‘Search-UnifiedAuditLog’ provides access to Microsoft 365 users’ login history from the last 180 days. However, it will provide limited details and won’t provide info about whether it’s interactive or non-interactive, MFA details, sign-in risk level, etc.

Graph PowerShell: You can use the Get-MgAuditLogSignin cmdlet to retrieve Entra ID sign-in logs with PowerShell. However, distinguishing between successful and failed login attempts can pose a challenge. Also, it can only retrieve data from the last 30 days.

To address this, we’ve developed a PowerShell script that allows you to schedule and store sign-in data for a longer period. It also exports detailed sign-in activities of Microsoft 365 users. This includes information such as sign-in date, location, device name, browser, operating system, authentication details, etc.

Script Highlights

  • Exports all Entra ID sign-in logs in user-friendly format.
  • Allows you to find out successful and failed sign-in attempts separately.
  • Filters interactive/non-interactive user sign-ins.
  • Helps export risky sign-ins alone.
  • Tracks guest users’ sign-in history.
  • Segments sign-in attempts based on Conditional Access applied & not applied.
  • Helps to monitor CA policy sign-in failures & success separately.
  • You can export the report to choose either ‘All users’ or ‘Specific user(s)’.
  • The script uses MS Graph PowerShell and installs MS Graph Beta PowerShell SDK (if not installed already) upon your confirmation.
  • The script can be executed with an MFA-enabled account too.
  • Exports report results as a CSV file.
  • The script is scheduler friendly.
  • It can be executed with certificate-based authentication (CBA) too.

Microsoft 365 Users Sign-in Activity Report – Script Execution Steps

  1. Download the script.
  2. Start the Windows PowerShell.
  3. Select any of the methods provided to execute the script.

Method 1: You can run the script with MFA and non-MFA accounts.

The example provided enables you to export Entra sign-in logs into a CSV file for the last 30 days. In addition, it’s essential to retrieve each user’s last logon time across the Microsoft 365 environment. This helps identify inactive users within the organization.

Method 2: You also have the option to run the script using certificate-based authentication, which is scheduler-friendly. When you want to run the script unattended, you can choose this method.
To use certificates, you must register the app in Microsoft Entra and connect to MS Graph using certificate.

Note: Depending on your requirements, you can create a self-signed certificate. Before employing certificate-based authentication, it is crucial to register an application in Azure AD.

Exploring Script Features

The script features predefined filters to meet your specific needs, excelling in these scenarios:

Note: The script retrieves sign-in data using the Get-MgBetaAuditLogSignin cmdlet and then filter the log based on the parameters you provide.

List Users with Risky Sign-ins in Microsoft 365

Risky sign-ins could indicate potential threats, such as compromised accounts or malicious activities. By monitoring and analyzing these sign-ins, you can take proactive measures to protect your organization and respond swiftly to security incidents. Using the script with –RiskySignInsOnly parameter, you can generate a report that lists all users with risky sign-ins, enabling you to address vulnerabilities promptly.

This script generates a report of all users with risky sign-ins.

Export Microsoft 365 Guest User Sign-in Report

By keeping track of when and where guest users access your Microsoft 365 resources, you can identify unusual activity, enforce policies, and improve overall compliance. By using the – GuestUserSignInsOnly parameter, you can generate a comprehensive report that details all sign-in activities by guest users.

This script generates a report of sign-in activities for all external users in your Microsoft 365 environment. You can also use the last login time to identify inactive guest users.

Export Interactive Sign-ins in Microsoft Entra ID

Focusing on interactive sign-ins helps you understand user-initiated activities, providing insights into how users engage with your Microsoft Entra ID environment. To export interactive sign-ins, execute the script with – InteractiveOnly switch param.

This script generates a report of interactive sign-ins in Microsoft Entra ID.

Export Azure AD Non-Interactive Sign-ins

Non-interactive sign-ins are sign-ins performed by a client app or an OS component on a user’s behalf. Understanding access patterns allows you to gain insights into how applications and services interact within Azure AD. Run the script with the –NonInteractiveOnly switch parameter.

The generated result produces a report of non-interactive user sign-ins in Azure AD.

View Entra Users’ Successful Sign-in Attempts

Real-time monitoring of successful sign-ins is crucial for swiftly verifying legitimate access and detecting unauthorized activities. Run the script with –Success parameter to list users with successful Entra ID sign-ins.

This script provides a report of successful Entra ID sign-in activities for users.

Identify Microsoft 365 Users’ Failed Sign-in Attempts

Monitoring failed sign-in attempts in your Microsoft 365 environment is crucial for several reasons. It helps analyze recurring patterns that may indicate systematic issues or targeted attacks, troubleshoot authentication problems promptly, and detect potential security threats. To get a list of failed Entra ID sign-ins, you can run the script with the –Failure parameter.

This result has a report of unsuccessful Entra ID sign-in attempts for users in Microsoft 365

Retrieve CA Policies Applied Sign-ins

By identifying sign-in attempts with applied Conditional Access policies, organizations can enforce granular access controls based on user context and device compliance. To retrieve a list of sign-in attempts with applied Conditional Access policies, execute the script with the -CAPAppliedOnly parameter.

The result captures both successful and failed Conditional Access login attempts.

Retrieve Sign-in Attempts without CA Policy

Identifying sign-ins without applied Conditional Access policies allows administrators to review and enforce necessary access controls, reducing the risk of unauthorized access. To retrieve a list of sign-ins without Conditional Access policies, execute the script with the –CAPNotAppliedOnly parameter.

The result shows all sign-ins without Conditional Access enforcement.

If you are particularly looking to monitor all CA policies in your organization, you can utilize this PS script to export Conditional Access policies to Excel.

Track Successful CA Policy Enforcement in Entra Sign-in Logs

By monitoring successful policy enforcement during sign-ins, you can verify effective security measures and ensure that access controls function correctly. To export a list of successful sign-ins using CA policies, execute the script with the -CAPSuccessOnly parameter:

This command generates a report listing all successful sign-ins based on Conditional Access policies.

Track Conditional Access Sign-in Failures in Entra

Tracking Conditional Access policy failures during sign-ins addresses vulnerabilities, such as policy misconfigurations or unauthorized access attempts. To export a list of sign-ins which failed due to a CA policy, run the script with the –CAPFailedOnly parameter.

This command identifies sign-ins that failed due to a conditional access policy.

Get Login History for a Specific User

Monitoring the sign-in activities of individual users helps detect unauthorized access attempts or suspicious activities associated with a specific user account. To export a specific user’s sign-in history, execute the script with the –UserPrincipalName param.

The exported report contains sign-in activity details of Alex.

Export Microsoft 365 Sign-in Details for a List of Users

If you want to get an Office 365 sign-in report for multiple users, you can pass usernames using the –UserPrincipalName param as comma-separated values.
